Answer:

For 135 students , the number of teacher requires is 9

Step-by-step explanation:

Given as :

The number of teacher = 6

The number of student  = 90

∵     For 90 students , the number of teacher requires = 6

So , For 1 student , the number of teacher requires = \frac{6}{90}

                                                                                     = \frac{1}{15}

∴   For 135 student , the number of teacher requires =  \frac{1}{15}×135

Or, For 135 student , the number of teacher requires =  \frac{135}{15}

So, For 135 student , the number of teacher requires = 9

Hence For 135 students , the number of teacher requires is 9   Answer

Can someone explain or help me out
Akimi4 [234]

Answer:

The bird has to fly 7.5 m

Step-by-step explanation:

Please see diagram in attached image.

Notice that there is a right angle triangle that defines the situation, and you know two elements of such triangle;

1) one acute angle (15^o), and

2) the side opposite to that angle.

What you need to find is the side adjacent to the angle, which is what the bird needs to fly horizontally to be above the fish. We named that "x".

The trig function that relates such triangle elements is the tangent:

tan(\theta)=\frac{opposite}{adjacent} \\tan(15^o)=\frac{2\,m}{x} \\x=\frac{2\,m}{tan(15^o)} \\x=7.46 \,\,m

which rounded to the nearest tenth is: 7.5 m

How much money has to be invested at 2.9% interest compounded continuosly to have 34,000 after 18 years
navik [9.2K]

Answer:

\$20,173.31  

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

t=18\ years\\ A=\$34,000\\ r=0.029  

substitute in the formula above  

34,000=P(e)^{0.029*18}  

P=34,000/((e)^{0.029*18})=\$20,173.31
